Can you make a wireless usb webcam?

I was looking for a wireless security camera, cheap though, so that i could attach it to my R/C tank (remote controlled tank with an airsoft cannon, that i upgraded to 800 psi on average) so i have a security system. So i found a USB webcam for $39.99. I was wondering if i could attach it to the tank then make it wireless. Or do they make wireless webcams? thanks.
